Aussie Olympic swimmer Cate Campbell has given power napping a whole new meaning after doing damage to a wrist joint during some quality shut-eye (you can read about those benefits here).

On Monday the former 100-metre freestyle world champion revealed she damaged her wrist last week, twice bending it backwards while sleeping.

"I am an aggressive napper," Campbell joked at the Rio Olympic swimming trials in Adelaide.

"When I get tired I sleep [on a bent wrist] and I woke up with it sore in the morning and then I went for a big old nap during the day and slept on it again and that did it."

Hoping to shave off as much time at Olympic Trials as I did off my hair today! Thanks @nakhair for giving me the chop!

Campbell's sister, Bronte -- another star in the pool -- managed to have a laugh during the trials too, dubbing her sister "talented" over the napping injury.

“No-one else seems to be able to do that, she’s an interesting thing. Even when she’s not doing anything she injures herself.’’

But Campbell overcame the injury during her first swim in the 100 metre freestyle heats, winning her heat with a 32.25 second race while Bronte swam a 53.73 second race.

We are down 7 teeth between the two of us. At least we are suffering together @bronte_campbell! #wisdomteeth

Campbell's wrist will need to survive another four days of trials, but the swimmer said she'll take local anaesthetic if the pain becomes too much.

The champion swimmer is also receiving intense physiotherapy, but did not discuss whether her napping posture has been addressed.
